The Legend of Zelda: Ocarina of Time - Saria's Song

Saria's Song is one with many uses, with its main function to allow Link to communicate with Saria wherever he is. It is taught to Link by Saria when he visits the Sacred Forest Meadow as a child, after already visiting Goron City. It is used twice during the story as a means of moving on, as well as obtaining a Piece of Heart. When used normally, Saria will contact you and offer you advice on what to do or where to go next.
